Answer:

Zero

Step-by-step explanation:

3x - 7 = 3x - 9 + 2

3x - 7 = 3x - 7

Add 7 on both sides

3x = 3x

Subtract 3x you get 0.

Hope this helps.

Answer:

  x = 10·cos(θ) -4·cot(θ)

Step-by-step explanation:

Apparently, we are to assume that the horizontal lines are parallel to each other.

The relevant trig relations are ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

If the junction point in the middle of AB is labeled X, then we have ...

  sin(θ) = 4/BX   ⇒   BX = 4/sin(θ)

  cos(θ) = x/XA   ⇒   XA = x/cos(θ)

Then ...

  BX +XA = AB = 10

Substituting for BX and XA using the above relations, we get

  4/sin(θ) +x/cos(θ) = 10

Solving for x gives ...

  x = (10 -4/sin(θ))·cos(θ)

  x = 10·cos(θ) -4·cot(θ) . . . . . simplify

_____

We used the identity ...

   cot(θ) = cos(θ)/sin(θ)

A TV screen is 15 in. high and 20 in. wide. Write a ratio of the TV's width to height.
lubasha [3.4K]

Answer:Height to width   is 3:4

Width to height   is 4:3

Step-by-step explanation:

A TV screen is 15 inches high and 20 inches wide.

Height of TV screen is 15 inches

Width of TV screen is 20 inches

To find ratio of Height to width

we replace the numbers in the ratio Height : width

15: 20

Divide both numbers by 5, so ratio becomes

3: 4

Height to width   is 3:4

To find ratio of  Width to height

we replace the numbers in the ratio Width : height

20:15

Divide both numbers by 5, so ratio becomes

4:3

Width to height   is 4:3
